TURBIDITY SENSORS

TURBIDITY SENSORSMODELS TS100 & TS300The Greenspan Turbidity Sensors provideaccurate and precise turbidity readings over arange of adverse environmental conditions.An innovative optical system providesaccurate measurements even at lowturbidities, while the advanced optical surfacetreatment resists fouling.

Make more accurate turbiditymeasurements with Greenspan’sstate of the art turbidity sensorTS100The Greenspan Turbidity Sensor offers a unique combination ofsuperior features:■■■Highly sensitive system based on array of high gain infraredoptics provides excellent accuracy at low turbidities.Exceptional ambient light rejection is achieved with infraredtransmission modulation.Advanced polymer coating of optical system resists fouling andminimises field maintenance requirements.■ Digital temperature compensation technology ensures stableperformance over a wide temperature range.The Greenspan turbidity sensor design is based upon an infraredemitter and receiver module and an electronic detection andmeasurement unit. The optical system transmits an infrared beamof 860nm and detects the backscatter intensity to determineturbidity.Greenspan ReliabilityExperience has shown that the major factor in accurate continuousmonitoring of turbidity is the cleanliness of the optical lens.Greenspan has coated the lens with a state of the art polymer toreduce any material or growth adhering to the optical face, thusprolonging the interval between site visits.Greenspan AccuracyAccurate and stable turbidity readings are ensuredthrough the use of Greenspan’s advanced filteringtechniques to eliminate interfering light sources. Boththe optical geometry and infrared wavelength conformto ISO 7027 “Method by measurement of attenuatedradiation”. Temperature compensation is achieved witha sophisticated digital sampling technique to respondinstantly to possible temperature induced errors.Greenspan turbidity sensors havebeen used for effluent monitoring,river and stream measurements,estuaries and runoff studies, forestryand catchment monitoring.A 316-grade stainlesssteel tube with o-ringsealed delrin endfittings provides theTS100 and TS300 withthe ruggednessrequired for the mostdemanding measurementenvironments.For particularly harshor corrosive environments,the TS100 andTS300 can be suppliedwith a complete Delrinbody.RELIABILITY • ACCURAC

Log accurate turbidity measurementscost-effectively with Greenspan’sversatile intelligent turbidity sensorTS300Greenspan’s Intelligent Turbidity Sensor model TS300 is a complete,self-contained turbidity measurement and data logging system.The TS300 adds sophisticated and versatile data acquisition, controland communications capabilities to Greenspan’s standard TS100Turbidity Sensor. Standard features of the TS300 include:■ Storage of measured data within the sensor for long periods.■ Easy configuration of logging parameters and uploading of loggeddata.■ Automatic transfer of data to a central office simply by attachinga data modem and mobile phone.■ Improved linearity and accuracy through the use of microprocessorbased compensation.■ Facility to set alarm conditions which can trigger additionalmeasuring equipment.With all the features ofa conventional dataacquisition system inone compact package,the Greenspan300-Series intelligentsensors provide themost cost-effectivesolution available todaywhere combinedmeasurement and datacollection functionsare required.■ Lithium battery pack option for fully self contained operation.The added features of the TS300 are accommodated within thesame compact sensor body used for the TS100. A separate datalogger and weatherproof housing are not required, eliminating theadded deployment costs normally associated with providing a remotedata logging capability, Simplified wiring means easier installationand maintenance also.Sophisticated communication features in the TS300 makeremote site logging of water turbidity easier than ever. In combinationwith an external data modem and mobile phone, the TS300enables remote uploading of logged data and re-programming oflogging schedules. In addition the TS300 can respond to userprogrammedalarm conditions by triggering an associated sensoror by calling one of four preset phone numbers with a userprogrammedalarm message.The TS300 provides an output to trigger a water sampler whereEPA legislation regulates maximum turbidity levels in catchments.The TS300 can be powered using either external batteries (via thesensor cable) or with Greenspan’s optional lithium batterypack, which can be fitted as an extension to the sensor body,making a fully self-contained measurement and logging system.Logging parameters andschedules are set upusing Greenspan’s easyto use graphical softwarepackage, Smartcom,which runs on IBMcompatible PCs.Graphical resprentationof data can be made usingGreenspan’s Aquagraphsoftware. The softwareamkes graphing your datasimple and allows data tobe exported in differentformats.Y • TECHNICALSUPPORT
